Songs that we didnt like, then...
There were many songs like this for me from the 80's and 90's only in 2000's I started accepting all songs. For example I never used to like 'Sonnapadi Kelu' from Singaravelan when it was released and used to skip the song whenever I played the tape. But now I find this song a great experimental song for a fun situation with brilliant orchestration. There may be other songs too like this from many of his albums. Please share the initial disliking and what made you like it later.
One other song which comes to my mind instantly is 'Edakku mudakkana sarakku' from 'Kalaignan' later when I came to understand the Rock elements in this songs I was amazed at my own ignorance.
